Herbicidal thiophene ketones

ABSTRACT

Compounds of Formula I and their agriculturally suitable salts are disclosed which are useful for controlling undesired vegetation ##STR1## wherein Q is ##STR2## and R 1  through R 7 , m, n, p and q are as defined in the disclosure. 
     Also disclosed are compositions containing the compounds of Formula I and a method for controlling undesired vegetation which involves contacting the vegetation or its environment with an effective amount of a compound of Formula I.

BACKGROUND OF THE INVENTION

This invention relates to certain thiophene ketones, their agriculturally suitable salts and compositions, and methods of their use for controlling undesirable vegetation.

The control of undesired vegetation is extremely important in achieving high crop efficiency. Achievement of selective control of the growth of weeds especially in such useful crops as rice, soybean, sugar beet, corn (maize), potato, wheat, barley, tomato and plantation crops, among others, is very desirable. Unchecked weed growth in such useful crops can cause significant reduction in productivity and thereby result in increased costs to the consumer. The control of undesired vegetation in noncrop areas is also important. Many products are commercially available for these purposes, but the need continues for new compounds which are more effective, less costly, less toxic, environmentally safer or have different modes of action.

EP 283,261 discloses heterocycles of Formula i as herbicides: ##STR3## wherein X, X¹ and X² are independently O or S;

The term "halogen", either alone or in compound words such as "haloalkyl", includes fluorine, chlorine, bromine or iodine. The term "1-4 halogen" indicates that one to four of the available positions for that substituent may be halogen. Further, when used in compound words such as "haloalkyl", said alkyl may be partially or fully substituted with halogen atoms which may be the same or different.

When a compound is substituted with a substituent beating a subscript that indicates the number of said substituents can exceed 1, said substituents (when they exceed 1 ) are independently selected from the group of defined substituents.

When a group contains a substituent which can be hydrogen, for example R² or R⁶, then, when this substituent is taken as hydrogen, it is recognized that this is equivalent to said group being unsubstituted.

Compounds of this invention can exist as one or more stereoisomers. The various stereoisomers include enantiomers, diastereomers, atropisomers and geometric isomers. One skilled in the art will appreciate that one stereoisomer may be more active and/or may exhibit beneficial effects when enriched relative to the other stereoisomer(s) or when separated from the other stereoisomer(s). Additionally, the skilled artisan knows how to separate and/or to selectively prepare said stereoisomers. Accordingly, the present invention comprises compounds selected from Formula I and agriculturally suitable salts thereof. The compounds of the invention may be present as a mixture of stereoisomers, individual stereoisomers, or as an optically active form.

Some compounds of this invention can exist as one or more tautomers. One skilled in the art will recognize, for example, that compounds of Formula Ia (Formula I where Q is Q-1, R³ is OR⁹, and R⁹ is H) can also exist as the tautomers of Formulae Ib and Ic as shown below. One skilled in the art will recognize that said tautomers often exist in equilibrium with each other. As these tautomers interconvert under environmental and physiological conditions, they provide the same useful biological effects. The present invention includes mixtures of such tautomers as well as the individual tautomers of compounds of Formula I. ##STR6##

The salts of the compounds of the invention include acid-addition salts with inorganic or organic acids such as hydrobromic, hydrochloric, nitric, phosphoric, sulfuric, acetic, butyric, fumaric, lactic, maleic, malonic, oxalic, propionic, salicylic, tartaric, 4-toluenesulfonic or valerie acids.

The definitions of Q, R¹ through R⁹, m, n, p and q in the compounds of Formulae I-XVI below are as defined above in the Summary of the Invention. Compounds of Formulae Ia-Ie are various subsets of the compounds of Formula I, and all substituents for Formulae Ia-Ie are as defined above for Formula I. Compounds of Formula Id and Ie correspond to Formula I compounds wherein Q is Q-1 and Q-2, respectively. ##STR7##

The coupling is carried out by methods known in the art (or by obvious modifications of these methods): for example, see K. Nakamura, et al., WO 95/04054. ##STR8##

Scheme 2 illustrates the preparation of compounds of Formula Id (R³ =SO_(r) R¹¹ ; r=1 or 2; and R¹¹ =C₁ -C₆ alkyl or C₁ -C₆ haloalkyl) whereby a compound of Formula Id (R³ =SR¹¹) is reacted with an oxidizing reagent such as peroxyacetic acid, m-chloroperoxybenzoic acid, peroxytrifluoroacetic acid, potassium peroxymonosulfate or hydrogen peroxide. The oxidation is carried out by methods known in the art (or by obvious modifications of these methods); for example, see S. Patai, et al., The Chemistry of Sulphones and Sulphoxides, John Wiley & Sons. ##STR9##

Compounds of Formula Id (R³ =Nu; Nu=SR¹¹ or OR¹² ; R¹¹ is as defined previously; R¹² is C₁ -C₆ alkyl, C₁ -C₆ haloalkyl or C₂ -C₆ alkoxyalkyl) can be prepared by one skilled in the art from a compound of Formula Id (R³ =halogen) by treatment with a nucleophile of Formula III (Nu=SR¹¹ or OR₁₂ ; M=Na, K, or Li) as shown in Scheme 3 using methods well documented in the literature (or obvious modifications of these methods): for example, see P. H. Nelson, et al., Synthesis, (1992), 12, 1287-1291; and S. Miyano, et al., J. Chem. Soc. Perkin Trans 1, (1976), 1146. ##STR10##

Compounds of Formula Id (R³ =halogen) can be prepared by reacting a compound of Formula Id (R³ =OH) with a halogenating reagent such as oxalyl bromide or oxalyl chloride (Scheme 4). This conversion is carried out by methods known in the art (or by obvious modifications of these methods): for example, see S. Muller, et al., WO 94/13619; S. Muller, et al., DE 4241999-A1. ##STR11##

Scheme 5 illustrates the preparation of compounds of Formula Id (R³ =OH) whereby an enol ester of Formula IV is reacted with a base such as triethylamine in the presence of a catalytic amount of a cyanide source (e.g., acetone cyanohydrin or potassium cyanide). This rearrangement is carried out by methods known in the art (or by obvious modifications of these methods): for example, see W. J. Michaely, EP 369,803. ##STR12##

Enol esters of Formula IV can be prepared by reacting a dione of Formula V with an acid chloride of Formula VI in the presence of a slight mole excess of a base such as triethylamine in an inert organic solvent such as acetonitrile, methylene chloride or toluene at temperatures between 0° C. and 110° C. (Scheme 6). This type of coupling is known in the art: for example, see W. J. Michaely, EP 369,803. ##STR13##

The acid chlorides of Formula VI can be prepared by reacting an acid of Formula VII with a halogenating reagent (e.g., oxalyl chloride or thionyl chloride) and a catalytic amount of dimethylformamide (Scheme 7). This chlorination is well known in the art: for example, see W. J. Michaely, EP 369,803. ##STR14##

Scheme 8 illustrates the preparation of acids of Formula VII (n=1 or 2) whereby an acid of Formula VII (n=0) is reacted with an oxidizing reagent such as peroxyacetic acid, m-chloroperoxybenzoic acid, peroxytrifluoroacetic acid, potassium peroxymonosulfate, or hydrogen peroxide. The oxidation is carried out by methods known in the art (or by obvious modifications of these methods): for example, see S. Patai, et al., The chemistry of Sulphones and Sulphoxides, John Wiley & Sons. For some acids of Formula VII (n=0) containing a functional group not compatible with the reaction conditions, the functional group may be protected before the oxidation and then be deprotected after the oxidation. The protection and deprotection procedures are well known in the literature: for example, see T. W. Greene, et al., Protective Groups in Organic Synthesis (Second Edition), John Wiley & Sons, Inc. ##STR15##

Scheme 9 illustrates the preparation of acids of Formula VII (n=0) whereby a bicyclic thiophene of Formula VIII is treated with a strong base such as n-butyllithium or lithium diisopropylamide (LDA) and the lithium salt generated in situ is then reacted with carbon dioxide followed by acidification with an acid such as hydrochloric acid. This conversion is carried out by methods known in the art (or by obvious modifications of these methods): for example, see S. Gronowitz., Heterocyclic Compounds Vol. 44, Part 5, John Wiley and Sons. Compounds containing functional groups not compatible with these reaction conditions may require protection and deprotection procedures. ##STR16##

Many bicyclic thiophenes of Formula VIII can be prepared (Scheme 10) by one skilled in the an by modifying the carbonyl functional group of bicyclic thiophenes of Formula VIIIa (p1=0, 1, 2, 3 or 4) using procedures well documented in the literature: for example, see I. T. Harrison, et al., Compendium of Organic Synthetic Methods, Vol. 1-7, John Wiley & Sons, Inc.; and T. W. Greene, et al., Protective Groups in Organic Synthesis (Second Edition), John Wiley & Sons, Inc. The functional group modifications include but are not limited to the following transformations:

convening a ketone to an oxime,

converting a ketone to a cyclic ketal,

reducing a ketone to an alcohol and then alkylating the alcohol to an alkyl ether,

reacting a ketone with an alkyl Grignard reagent (or an alkyl lithium reagent) to yield an alcohol and then alkylating the alcohol to an alkyl ether,

converting a ketone to a halogenated methylene group (through the alcohol intermediate if necessary), and

reducing a ketone to a methylene group. ##STR17##

Scheme 11 illustrates the preparation of bicyclic thiophenes of Formula VIII (R² is other than Br) whereby a bicyclic thiophene of Formula VIII (R² =Br) is reacted with n-butyllithium and the lithium salt generated in situ is then reacted with an electrophile (e.g., N,N-dimethylsulfamoyl chloride, N,N-dimethylformamide, or CO₂). The new R² group so generated can be further modified if necessary. ##STR18##

Scheme 12 illustrates the preparation of bicyclic thiophenes of Formula VIIIa (p1=0, 1, 2, 3 or 4) whereby a thiophenethioalkylcarboxylic acid of Formula IX (p1=0, 1, 2, 3 or 4) is treated with a dehydrating reagent such as sulfuric acid, polyphosphoric acid (PPA) or trifluoroacetic anhydride (TFAA). For details of the reaction conditions, please see W. Flemming, et al., Chem. Ber. (1925), 58, 1612; I. W. J. Still, et al., Can. J. Chem. (1976), 54, 453-470; V. J. Traynelis, et al., J. Org. Chem. (1961), 26, 2728; T. K. Jones, et al., J. Org. Chem. (1991), 56, 763-769. ##STR19##

Alternatively, the bicyclic thiophenes of Formula VIIIa (p¹ =0, 1, 2, 3 or 4) can be prepared (Scheme 13) by cyclizing (in the presence of a Lewis acid such as SnCl₄) the thiophenethioalkylcarbonyl chlorides of Formula X which are prepared/n situ from the thiophenethioalkylcarboxylic acids of Formula IX (p¹ =0, 1, 2, 3 or 4) by treatment with a chlorinating reagent such as oxalyl chloride (in the presence of a catalytic amount of N,N-dimethylformamide). This conversion is carried out by methods known in the art (or by obvious modifications of these methods): for example, see E. Dalgliesh, et al., J. Chem. Soc. (1945), 893; G. S. Ponticello, et al., J. Org. Chem. (1988), 53, 9-13. ##STR20##

The reaction mixture is then concentrated under reduced pressure. The residue is dissolved in an organic solvent such as methylene chloride or 1,2-dichloroethane and the organic solution is washed with an alkaline aqueous solution such as a 5% sodium bicarbonate aqueous solution. The organic layer is separated, dried over a drying agent such as MgSO₄ and concentrated to give the crude product. The crude product can be further purified by chromatography (e.g., silica gel/hexanes). ##STR21##

Thiophenethioalkylcarboxylic acids of Formula IX (p¹ =0, 1, 2, 3 or 4) can be prepared by methods known in the art (or by obvious modifications of these methods): for example, see G. S. Ponticello, et al., J. Org. Chem. (1988), 53, 9-13; T. K. Jones, et al., J. Org. Chem. (1991), 56, 763-769.

The displacement is carried out by methods known in the art (or by obvious modifications of these methods): for example, see J. Z. Mortensen, et al., Tetrahedron (1971), 27, 3831-3838; and K. I. Sadykhov, et al., Khim. Geterotsikl. Soedin. (1975), 344-345. ##STR22##

Thiophenethiol salts of Formula XII and alkenyl halides of Formula XIII are either commercially available or can be prepared by methods known in the art (or by obvious modifications of these methods).

This rearrangement is carried out by methods known in the art (or by obvious modifications of these methods): for example, see W. J. Michaely, EP 369,803. ##STR24##

Esters of Formula XV can be prepared by reacting a hydroxypyrazole of Formula XVI with an acid chloride of Formula VI in the presence of a slight mole excess of a base such as triethylamine in an inert organic solvent such as acetonitrile, methylene chloride or toluene at temperatures between 0° C. and 110° C. (Scheme 18). This type of coupling is carried out by methods known in the art (or by obvious modifications of these methods): for example, see W. J. Michaely, EP 369,803. ##STR25##

It is recognized that some reagents and reaction conditions described above for preparing compounds of Formula I may not be compatible with certain functionalities present in the intermediates. In these instances, the incorporation of protection/deprotection sequences or functional group interconversions into the synthesis will aid in obtaining the desired products. The use and choice of the protecting groups will be apparent to one skilled in chemical synthesis (see, for example, Greene, T. W.; Wuts, P. G. M. Protective Groups in Organic Synthesis, 2nd ed.; Wiley: New York, 1991). One skilled in the art will recognize that, in some cases, after the introduction of a given reagent as it is depicted in any individual scheme, it may be necessary to perform additional routine synthetic steps not described in detail to complete the synthesis of compounds of Formula I. One skilled in the art will also recognize that it may be necessary to perform a combination of the steps illustrated in the above schemes in an order other than that implied by the particular sequence presented to prepare the compounds of Formula I.

One skilled in the art will also recognize that compounds of Formula I and the intermediates described herein can be subjected to various electrophilic, nucleophilic, radical, organometallic, oxidation, and reduction reactions to add substituents or modify existing substituents.

Without further elaboration, it is believed that one skilled in the art using the preceding description can utilize the present invention to its fullest extent. The following Examples are, therefore, to be construed as merely illustrative, and not limiting of the disclosure in any way whatsoever. Percentages are by weight except for chromatographic solvent mixtures or where otherwise indicated. Parts and percentages for chromatographic solvent mixtures are by volume unless otherwise indicated. ¹ H NMR spectra are reported in ppm downfield from tetramethylsilane; s=singlet, d=doublet, t=triplet, q=quartet, m=multiplet, dd=doublet of doublets, dt=doublet of triplets, br s=broad singlet.

Formulation/Utility

Compounds of this invention will generally be used as a formulation or composition with an agriculturally suitable carrier comprising at least one of a liquid diluent, a solid diluent or a surfactant. The formulation or composition ingredients are selected to be consistent with the physical properties of the active ingredient, mode of application and environmental factors such as soil type, moisture and temperature. Useful formulations include liquids such as solutions (including emulsifiable concentrates), suspensions, emulsions (including microemulsions and/or suspoemulsions) and the like which optionally can be thickened into gels. Useful formulations further include solids such as dusts, powders, granules, pellets, tablets, films, and the like which can be water-dispersible ("wettable") or water-soluble. Active ingredient can be (micro)encapsulated and further formed into a suspension or solid formulation; alternatively the entire formulation of active ingredient can be encapsulated (or "overcoated"). Encapsulation can control or delay release of the active ingredient. Sprayable formulations can be extended in suitable media and used at spray volumes from about one to several hundred liters per hectare. High-strength compositions are primarily used as intermediates for further formulation.

The formulations will typically contain effective amounts of active ingredient, diluent and surfactant within the following approximate ranges which add up to 100 percent by weight.

Typical solid diluents are described in Watkins, et al., Handbook of Insecticide Dust Diluents and Carriers, 2nd Ed., Dorland Books, Caldwell, N.J. Typical liquid diluents are described in Marsden, Solvents Guide, 2nd Ed., Interscience, N.Y., 1950. McCutcheon's Detergents and Emulsifiers Annual, Allured Publ. Corp., Ridgewood, N.J., as well as Sisely and Wood, Encyclopedia of Surface Active Agents, Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth and the like, or thickeners to increase viscosity.

Surfactants include, for example, polyethoxylated alcohols, polyethoxylated alkylphenols, polyethoxylated sorbitan fatty acid esters, dialkyl sulfosuccinates, alkyl sulfates, alkylbenzene sulfonates, organosilicones, N,N-dialkyltaurates, lignin sulfonates, naphthalene sulfonate formaldehyde condensates, polycarboxylates, and polyoxyethylene/polyoxypropylene block copolymers. Solid diluents include, for example, clays such as bentonite, montmorillonite, attapulgite and kaolin, starch, sugar, silica, talc, diatomaceous earth, urea, calcium carbonate, sodium carbonate and bicarbonate, and sodium sulfate. Liquid diluents include, for example, water, N,N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolidone, ethylene glycol, polypropylene glycol, paraffins, alkylbenzenes, alkylnaphthalenes, oils of olive, castor, linseed, tung, sesame, corn, peanut, cotton-seed, soybean, rape-seed and coconut, fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy-4-methyl-2-pentanone, and alcohols such as methanol, cyclohexanol, decanol and tetrahydrofurfuryl alcohol.

Solutions, including emulsifiable concentrates, can be prepared by simply mixing the ingredients. Dusts and powders can be prepared by blending and, usually, grinding as in a hammer mill or fluid-energy mill. Suspensions are usually prepared by wet-milling; see, for example, U.S. Pat. No. 3,060,084. Granules and pellets can be prepared by spraying the active material upon preformed granular carriers or by agglomeration techniques.

Test results indicate that the compounds of the present invention are highly active preemergent and postemergent herbicides or plant growth regulants. Many of them have utility for broad-spectrum pre- and/or postemergence weed control in areas where complete control of all vegetation is desired such as around fuel storage tanks, industrial storage areas, parking lots, drive-in theaters, air fields, river banks, irrigation and other waterways, around billboards and highway and railroad structures. Some of the compounds are useful for the control of selected grass and broadleaf weeds with tolerance to important agronomic crops which include but are not limited to alfalfa, barley, cotton, wheat, rape, sugar beets, corn (maize), sorghum, soybeans, rice, oats, peanuts, vegetables, tomato, potato, perennial plantation crops including coffee, cocoa, oil palm, rubber, sugarcane, citrus, grapes, fruit trees, nut trees, banana, plantain, pineapple, hops, tea and forests such as eucalyptus and conifers (e.g., loblolly pine), and turf species (e.g., Kentucky bluegrass, St. Augustine grass, Kentucky fescue and Bermuda grass). Those skilled in the art will appreciate that not all compounds are equally effective against all weeds. Alternatively, the subject compounds are useful to modify plant growth.

Compounds of this invention can be used alone or in combination with other commercial herbicides, insecticides or fungicides. Compounds of this invention can also be used in combination with commercial herbicide safeners such as benoxacor, dichlormid and furilazole to increase safety to certain crops.

In certain instances, combinations with other herbicides having a similar spectrum of control but a different mode of action will be particularly advantageous for preventing the development of resistant weeds. Compounds of the sulfonylurea, imidazolinone and triazolopyrimidine classes as well as benzoic acids and phenoxy compounds are contemplated. The preferred mixing partners are selected from the group rimsulfuron, nicosulfuron, chlorimuron ethyl, imazethapyr and dicamba. Most preferred mixing partners are rimsulfuron and imazethapyr.

An herbicidally effective amount of the compounds of this invention is determined by a number of factors. These factors include: formulation selected, method of application, amount and type of vegetation present, growing conditions, etc. In general, a herbicidally effective amount of compounds of this invention is 0.001 to 20 kg/ha with a preferred range of 0.004 to 1.0 kg/ha. One skilled in the art can easily determine the herbicidally effective amount necessary for the desired level of weed control.

The following Tests demonstrate the control efficacy of the compounds of this invention against specific weeds. The weed control afforded by the compounds is not limited, however, to these species.

BIOLOGICAL EXAMPLES OF THE INVENTION TEST A

Seeds of barley (Hordeurn vulgare), barnyardgrass (Echinochloa crus-galli), bedstraw (Galium aparine), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), cocklebur (Xanthium strumarium), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria sanguinalis), downy brome (Bromus tectorum), giant foxtail (Setaria faberii), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), rape (Brassica napus), rice (Oryza saliva), sorghum (Sorghum bicolor), soybean (Glycine max), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), wild oat (Avena fatua) and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with test chemicals formulated in a non-phytotoxic solvent mixture which included a surfactant.

At the same time, these crop and weed species were also treated with postemergence applications of test chemicals formulated in the same manner. Plants ranged in height from two to eighteen cm (one to four leaf stage) for postemergence treatments. Treated plants and controls were maintained in a greenhouse for twelve to sixteen days, after which all species were compared to controls and visually evaluated.

TEST B

The compounds evaluated in this test were formulated in a non-phytotoxic solvent mixture which included a surfactant and applied to the soil surface before plant seedlings emerged (preemergence application), to water that covered the soil surface (flood application), and to plants that were in the one-to-four leaf stage (postemergence application). A sandy loam soil was used for the preemergence and postemergence tests, while a silt loam soil was used in the flood test. Water depth was approximately 2.5 cm for the flood test and was maintained at this level for the duration of the test.

Plant species in the preemergence and postemergence tests consisted of barnyardgrass (Echinochloa crus-galli), barley (Hordeurn vulgare), bedstraw (Galium aparine), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), cocklebur (Xanthium strumarium), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria sanguinalis), downy brome (Bromus tectorum), giant foxtail (Setaria faberii), johnsongrass (Sorghum halepense), lambsquarters (Chenopodium album), morningglory (Ipomoea hederacea), pigweed (Amaranthus retrofiexus), rape (Brassica napus), ryegrass (Lolium multiflorum), soybean (Glycine max), speedwell (Veronica persica), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygonurn convolvulus), and wild oat (Avena fatua). All plant species were planted one day before application of the compound for the preemergence portion of this test. Plantings of these species were adjusted to produce plants of appropriate size for the postemergence portion of the test. Plant species in the flood test consisted of rice (Oryza saliva), umbrella sedge (Cyperus difformis), duck salad (Heteranthera limosa), barnyardgrass (Echinochloa crus-galli) and late watergrass (Echinochloa oryzicola) grown to the 2 leaf (2 L) stage for testing.

All plant species were grown using normal greenhouse practices. Visual evaluations of injury expressed on treated plants, when compared to untreated controls, were recorded approximately fourteen to twenty one days after application of the test compound. Plant response to the test compound are summarized in Table B, recorded on a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

TEST C

Compounds evaluated in this test were formulated in a non-phytotoxic solvent mixture which included a surfactant, applied to the soil surface before plant seedlings emerged (preemergence application) and to plants that were in the one-to four leaf stage (postemergence application). A sandy loam soil was used for the preemergence test while a mixture of sandy loam soil and greenhouse potting mix in a 60:40 ratio was used for the postemergence test. Test compounds were applied within approximately one day after planting seeds for the preemergence test.

Plantings of these crops and weed species were adjusted to produce plants of appropriate size for the postemergence test. All plant species were grown using normal greenhouse practices. Crop and weed species include annual bluegrass (Poa annua), black nightshade (Solanum nigra), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), deadnettle (Lamium amplexicaule), downy brome (Bromus tectorum), field violet (Viola arvensis), galium (Gatium aparine), green foxtail (Setaria viridis), jointed goatgrass (Aegilops cylindrica), kochia (Kochia scoparia), lambsquarters (Chenopodium album), littleseed canarygrass (Phalaris minor), rape (Brassica napus), redroot pigweed (Amaranthus retroflexus), ryegrass (Lolium multifiorum), scentless chamomile (Matricaria inodora), speedwell (Veronica persica), spring barely (Hordeum vutgare cv. `Klages`), spring wheat (Triticum aestivum cv. `ERA`), sugar beet (Beta vulgaris cv. `US1`), sunflower (Helianthus annuus cv. `Russian Giant`), wild buckwheat (Polygonum convolvulus), wild mustard (Sinapis arvensis), wild oat (Avena fatua), windgrass (Apera spica-venti), winter barley (Hordeurn vutgare cv. `Igri`) and winter wheat (Triticum aestivum cv. `Talent`).

Treated plants and untreated controls were maintained in a greenhouse for approximately 21 to 28 days, after which all treated plants were compared to untreated controls and visually evaluated. Plant response ratings, summarized in Table C, are based upon a 0 to 100 scale where 0 is no effect and 100 is complete control. A dash response (-) means no test result.
